One of the parts I'm working on needs a big (0.150" diagonal) 45deg chamfer around a contour. I looked around my tool tray (just kidding, they're all over the place) and thought a 1/2" spot drill might work. It's what I normally use for chamfering, but I had never done a chamfer that wasn't just breaking the edge.
Anyway - it SORT of worked, but not well. I think I missed the ideal feedrate by A LOT, the tool rubbed and made a horrible mess. I'm sure I can improve it by doubling the feedrate (I was at 2500 and 15ipm..) but it still feels like it isn't the ideal tool, at all. A ball end mill and some creative programming might work better, but what's the simple solution I'm missing here? :) I'm sure there's an easy way of doing this that I'm forgetting about.
Any thoughts?
